pata_xxx is for older PIIX, not ICH4. ICH* is handled by ata_piix, which
can drive both SATA *and* PATA in the new kernels. In fact:
[notting@nostromo: ~]$ lspci | grep IDE
00:1f.1 IDE interface: Intel Corporation 82801DBM (ICH4-M) IDE Controller (rev 01)
[notting@nostromo: ~]$ dmesg | grep ata
...
ata_piix 0000:00:1f.1: version 2.00ac6
ata1: PATA max UDMA/100 cmd 0x1F0 ctl 0x3F6 bmdma 0x1860 irq 14
ata2: PATA max UDMA/100 cmd 0x170 ctl 0x376 bmdma 0x1868 irq 15

[notting@nostromo: ~]$ uname -r
